PLOW GAUGE WHEEL.

Application filed February 3, 1921, Serial No. 442,164. Renewed October15, 1924.

To all whom it may concern:

Be it known that we, GUY DEN'BIGH and Roy WALKER, both of the town ofVulcan, in the Province of Alberta, Canada, have invented certain newand useful Improvements in Plow Gauge Wheels, of which the following isthe specification.

The invention relates-to improvements in plow gauge wheels andparticularly to the gauge wheels as used on engine gang plows and theobject of the invention is to provide a wheel wherein particularattention has been directed to the lubricating features, therebyavoiding unnecessary wear due to faulty lubrication, also the loss oftime and labor otherwise occasioned in making repairs.

A further object is to design the wheel and lubricating arrangementthereof such that the wheel will be self lubricating for a considerableperiod and the lubricating positive to all working parts.

A furtherobject is to construct the wheel so that it is, comparativelyspeaking, dust roof.

With the above objects in view the invention consists essentially in thearrangement and construction of parts hereinafter more particularly.described and later pointed out in the appended claims, reference beinghad to the accompanying drawing in which i Fig. 1' is a side view of aportion of an engine gang plow fitted with our invention.

Fig. 2 is an enlarged detailed side view of the gauge wheel.

Fig. 3 is an enlarged sectional view centrally through the gauge wheel,the section being taken at 33 Fig. 2.

Fig. 4 is a sectional view through the gauge wheel, the section beingtaken at 4.--4 Fig. 3 and considerably reduced.

Fig. 5 is a vertical sectional view at 5-5 Fig. 3 with the spring shownin side elevation.

Fig. 6 is an enlarged horizontal sectional view at 6-6 Fig. 3.

In the drawing like characters of reference indicate corresponding partsin the several figures.

1 represents the customary platform of a gang plow and 2 the plowsconnected in the ordinary way by the plow beams 3 to the platform, itbeing understood that the gang plow is pulled by a traction engine as iscustomary.

In connection with the plow beams, the forward ends of which arepivotally con nected to the platform'frame or draw beam, it is usualto'supply gauge wheels determining the depth of the plow out.

At the present time most of the gauge wheels met with in practice aregrease lubricated, the grease being fed by a grease cup to the* wearingparts of the gauge wheel. We have found from actual experience that sucha lubricating arrangement is not satisfactory as the gauge wheelsinvariably give trouble due to unsatisfactory lubrication and theconsequent wear occasioned. .Further, the wheels are not designed sothat they are dust proof and in sandy or light soils trouble isinvariably had due to the dust working into the bearings and damagingthe parts. 7 v

The object of our invention as already set forth is to provide a gaugewheel which can be substituted for the older forms and which Wlll notgive any trouble from a lubricating or wearing standpoint.

The gauge wheels 4. which we provide for the plow are all identicallyconstructed and each comprise the parts now described.

5 is a hollow wheel having the rim 6, hub 7 and sides 8 and 9 integrallycast and provided internally with a radially disposed cast web 10extending from the hub to the rim and between the sides 8 and 9. Thecore holes 11 of the wheels are covered by cover plates 12 attached tothe sides of the wheel by suitable screws, there being a gasket 13inserted to prevent leakage of oil from the interior of the wheel. Ascrew plug la is provided in the side 8 of the wheel which allows one toput oil into the hollow centre of the wheel to a. level of say four orfive inches.

The hub 7 receives a bushing 15 which can be removed from time to timeas occasion may demand and the bushin receives the wheel axle 16, theends of which project considerably beyond the sides of the wheel.

17 and 18 are two similar gland plates mounted on the axle at oppositesides of the wheel and fastened to the wheel by suitable screws 19having countersunk heads. The gland plates are formed with inwardlyextending bosses which bear against felt or such like washers 20 and 21mounted on the axle and positioned between the ends of the bushing andthe bosses.

"perien'ce'd in so far 1 as At the 19111391 a-faces ofithe land platesand on the axle we locate forkp lates EZfZ and 23 which have their outerfaces cross-slotted to receive the customary fo-1 'lre,d arms 2et and 25of th gsiuge wheel.
